泰国海洋共生清洁站，有海鳗和清洁虾

moray eel rests in its reef crevice as a bluestreak cleaner wrasse (Labroides dimidiatus) works over its skin and gill area, removing parasites and dead tissue in a cleaning symbiosis widespread across Indo-Pacific coral reefs. Cleaner wrasse are permitted close access to a moray's mouth and gills during these interactions, a notable trust behaviour between predator and a fish many times smaller than itself. Cleaning stations like this are key social hubs on reef ecosystems. Andaman Sea, Krabi Province, Thailand.
